House Democrats on Friday approved a sprawling bill to lower prescription drug costs, address global warming, raise taxes on some billion-dollar corporations and reduce the federal deficit, sending to President Biden the long-delayed, last component of his economic agenda in time for this year’s elections.

The 220-207 vote marked the culmination of roughly a year and a half of debate that at times pitted the party’s lawmakers against each other, revealing Democrats’ fierce ideological divides. In the end, though, the often-fractious caucus banded together to overcome unanimous Republican opposition, adopting a measure to improve Americans’ finances originally premised on Biden’s 2020 campaign pledge to “build back better.”
